Step-by-step explanation:</h2>
The graph of this parabola is shown below. From this graph we know that:
VERTEX:
DIRECTIX:
Since the vertex lies on the origin and the parabola opens upward, then the standard form of this parabola is:
So:
Then the directrix is:
Answer:
2,800 CUV cars were sold
Step-by-step explanation:
7 out of 10 are CUV
Total sold are 4,000
Set them equal to each other:
Cross multiply:
Solve for x:
x = 2,800
Step-by-step explanation:
(A)
Length of wire = 30.48 m
Area of cross section = 3.22 * 10 ^ -5 m^2
(B) length of wire = 1219.2 m
Area of cross section = 1.29 * 10^-5 m^2
Resistance = 8.45 * 10^-8 * 1219.2 / 1.29 * 10^-5 = 7.98 Ohms
The perimeter is 10 try to draw these points on the graph and count the distance between each or you can just look at the coordinates and find the distance and then add length and width
Answer:
40
Step-by-step explanation:
This could be wrong cause this is a concept question I don't know well but I think cause there is 8 sides and 8 angles 360/8=40
